K&N Direct-Fit Air Filter – 18,000 Mile | Saturn Outlook / GMC Acadia 3.6L V6 | KNA-2394

Non-washable long-life filter — this is a disposable replacement filter with an 18,000-mile service life. It is not a washable/reusable oiled gauze K&N filter.

K&N KNA-2394 direct-fit replacement air filter for the Saturn Outlook (2007–2010) and GMC Acadia (2007–2016) with the 3.6L V6. Drops into the factory airbox with no modification. 18,000-mile service interval. 1.44 lbs. Ships fast across Canada and the US.

18,000-Mile Service Life

The KNA-2394 uses a premium synthetic or cellulose-blend filter media rated for up to 18,000 miles of service — 50% longer than the standard 12,000-mile OEM replacement interval. For Outlook and Acadia owners on a regular maintenance schedule, this means one fewer filter change per 36,000-mile maintenance cycle compared to a standard OEM-spec filter. The extended service life is the primary advantage of the KNA series over a standard OEM replacement filter.

Non-Washable — Long-Life Disposable

The KNA-2394 is part of K&N’s non-washable filter line. Unlike K&N’s oiled cotton gauze performance filters (33- series) which are cleaned and re-oiled for reuse, the KNA-2394 is a long-life disposable filter — it is replaced at the end of its service interval, not cleaned. It provides 99% engine filtration efficiency and meets or exceeds OEM specifications for the 3.6L V6 application.

Direct-Fit OEM Airbox Replacement

The KNA-2394 is designed to the exact dimensions of the factory Saturn Outlook and GMC Acadia airbox filter element. Installation requires no tools, no modification to the airbox or intake system, and takes under 5 minutes — remove the airbox lid, pull the old filter, drop in the KNA-2394, reinstall the lid.
